I have a more pessimistic assessment.
During the height of the Covid-19 pandemic. Those Hanjians doubled, and then tripled down one their anti-China hatorade. These scum even went so far as to try to steer the Asian hate to focus more on the Chinese. Needless to say, the Hanjians will quadruple-down in a West-China conflict. Scum like Gordon Chang and Nathan Law are never gonna change their minds.
Asians are unfortunately also one of the worse offenders of racism. Many Asians would gladly join the China-hate. Koreans, Japanese, Filipinos, and most especially, Indians. Indians in America have been reported to had racially insult Americans of East Asian ethnicities.
The Chinese people have to toughen themselves to the inevitable escalation of racism against them. Don't be naive and hope for the hate to subside on it's own. For us overseas Chinese, we have to unite like never before. Doesn't matter if we love China or not, we must start to defend our communities and help those in need. Those Hanjian haters cannot be saved or forgiven. Just leave them to their own pathetic fate.
The Nathan Laws of the world are forever lost, and as such should be written off.
However, I've noticed a general trend of overseas asians becoming more pro-asian, anti-white as a result of the pandemic. This group makes up around 70-85% of ABC's IMO.
This is a move in the right direction, and from social media etc. you can see that they have a similar attitude to defending our communities as you mentioned above. What's better is that these groups are 'pan-asian', in that there is no Chinese vs Korean vs Japanese / East Asia vs SEA type BS that you might have seen pre-2020.
Self-haters only exist because they're searching far and wide for a source of self worth, and as the balance of power changes, you might see some Joshua Wong types becoming hardcore nationalists as they now have a new, intrinsic source of self worth.
Overall, I'm optimistic. There may be a few interesting years ahead, but I think the writing's on the wall.
